linux查看系统的硬件信息，并不像windows那么直观，这里我罗列了查看系统信息的实用命令，并做了分类，实例解说。
一、查看服务器硬件信息
（1）查看服务器型号、序列号
[root@Master ~]# dmidecode|grep "System Information" -A9|egrep "Manufacturer|Product|Serial"
（2）查看主板型号
[root@Master ~]# dmidecode |grep -A16 "System Information$"
3）查看BIOS信息
[root@Master ~]# dmidecode -t bios
# dmidecode 2。12
SMBIOS 2。8 present。
Handle 0x0008, DMI type 0, 24 bytes
